Proposed fix:

* Change box-shadow to text-shadow in this example, which is apparently 
what was intended.
* Add "(assuming a white background)" after "would cause the text to 
become invisible". This is the only reason the text would become 
invisible. Alternatively, add `background: white` to the rule.
